- DRINKING FOUNTAIN.

Specification of Letters Patent. P te t d r; 21, 1922;

Application filed December 8,1920. Serial No. 429,124L' attachable to or detachable from a faucet of the ordinary construction.

It is also a purpose of my invention to pro vide a drinking fountain which is adjustable to allow for different water pressures whereby, the proper flow of water through the fountain is insured irrespective of the water pressure. Furthermore, my invention provides means for deflecting the water within the fountain so as to create a rolling action of the stream and to thus allow the ready drinking of water from the fountain.

I will describe one form of fountain embodying my invention and will then point out the novel features thereof in claims.

In the accompanying drawings:

Fi ure 1 is a view showing in side elevation one form of fountain embodying my invention.

Figure 2 is a View similar to Figure 1 with portions of the fountain in vertical section.

Figures 3, 4; and 5 are transverse sectional views taken on the lines 33, and 5-5, respectively, and looking in the direction of the arrows. I

Similar reference characters refer similar parts in each of the several views.

Referring specifically to the drawings and particularly to Figures 1 and 2, my inven tion in its present embodiment comprises a substantially U-shaped length of pipe P, one arm of which is. provided with a union N preferably formed of rubber or other flexible material and having its lower end constricted to tightly embrace the upper end of the pipe P. The upper end of the union N is of greater diameter than the lower end and is adapted to receive the faucets (not shown) and to so embrace the same as to support the fountain as a unit upon the faucets, 1t being understood that the union provides a water-tight joint between the faucet and pipe P. The free extremity ofthe other arm of the pipe P is screw threaded exteriorly to adjustably receive the head of the fountain. The fountain head comprises in the present instance a casing 15 of the contour shown in Figures 1 and 2, and suitably secured within thecasing are discs or plates 16 and 17 The disc 17 is arranged in superposed relation with respect to the disc 16 and is provided axially thereof with an opening 17%through which the water from the pipe P is adapted to pass as will be more fully described hereinafter. The disc 16 is provided axially thereof with an opening, the walls of'which are screw-threaded to engage the] adjacent end of thepipe P, the disc being further provided with a plurality of perforations 16 as clearly shown in Figure 3 through which the waste water from the fountain is discharged. The disc 16 can be locked in any adjusted position upon the pipe P by means of a lock nut 18 which, as shown in Figure 2, engages the under-side of the disc 16 so as to prevent accidental rotation of the disc. By means of this adjustment, it will be clear that the vertical position of the fountain head as a unit can be varied so as to vary the distance between the end of the pipe P and the disc 17.

Within the casing 15 and normally resting uponthe disc 17 is a deflecting plate 19'provided on its under side with lugs 19 which constitute feet for supporting the plate in spaced relation to the disc 17. As shown in Figure 5, the plate 19 in the present instance is of disc formation and is provided with three lugs 19. The casing 15 is of substantiallv, frusto-conical formation, its upper end being formed with a drinking opening 20, the wall ofwhich is downturned to pro v-idea deflecting lip- 20 that is adapted to coact with theplate 19 in controlling the flow of water within the fountain head.

In the operation of the fountain, the pipe I P is secured to a faucet of standard form through the medium of the union N so that the fountain head is supported in vertical position as shown in Figures 1 and 2. The water discharged from the threaded end of the pipe P impinges upon the under side of the plate 17, a portion of the water passing through the restricted opening 17 where, it

engages and lifts the deflecting plate 19..

Under the action of the deflecting plate 19, the water is forced to pass to the. periphery of the plate and thence upwardly along the wall of the casing to the lip 20 The lip a the opening 17 20 being bent downwardly causes the water to be directed downwardly thus imparting a rolling action to the flow of water within the opening 20. Such movement of the water prevents its emission upwardly from the casingso that one in safety may drink from the openin 20. That water which is not discharged t rough the opening 17 is deflected downwardly by the plate 17 Where it exits from the fountain head'through the several perforations 16.

Should the pressure of water be excessive so that the deflecting plate 19 is thrown against the lip 20 so as to close the opening 20' and thus prevent the proper operation of the fountain, the fountain head is ad j'usted by a turning of the nut 18 to a disengaging position with respect to'the disc 16 thereby ermitting rotation oi. the head upon the pipe l so as to move the plate 17 a greater distance from the discharge end of the pipe P and to thereby lessen the force of the water passing through the opening 17. On the other hand should the pressure of water be insufiicient to discharge the necessary amount of water through the opening 17 to produce the desired flow within the opening 2-0, the fountain head can be adjusted downwardly upon the plateP so as to move the discharge end of the pipe in closer proximity to the plate 17. This obviously in-,

creases the amount of water passing through and impinging upon the plate 19. j

Although I have hereinshown and described only one form of drinking fountain embodying my invention, it is to be understood that various changes and modifications may be made herein without departing from the spirit of the invention and the spirit and scope of the appended claims.

What I claim is: i i

1. A drinking fountain comprising, a pipe, a fountain head supported on the upper end of the pipe and including a casing formed at its upperend with a drinking opening, the wall of which is bent downwardly to provide an inturned lip, a plate secured within the casing adjacent its base and formed with the second plate and spanning said discharge opening, and lugs formed on the deflecting plate for normally spacing said plate from the second plate. a.

2. A drinking fountain comprising, a pipe, a perforated plate threadedly engaging the upper end of the pipe, means for locking the plate in adjusted position, a casing secured to the plate, the upper end of said casing being formed with a' drinking opening, the wall of which is'downturned to provide a depending lip, a second plate fixed within the caslng at a point above the upper end of said pipe, a discharge opening formed in the.

second plate directly above the upper end of said pipe, and means between said drinking opening and the second plate adapted to cause the water passing upwardly through the discharge opening to spread and impinge upon the inner side of said lip for the purpose described. 1

3. A drinking fountain comprising, a pipe, a fountain head supported onone end of the pipe. and including a disc threadedly engaging the pipe and formed withperforations,

a tubular casing embracing thedisc, a sec-,

ond disc above the adjacent end of the pipe, at discharge opening. formed in the second disc, and disposed directly above theadjacent end of the pipe, a-deflecting plate resting on the second plate and spanning said discharge opening, and a circular depending lip formed on the upper end of the casing and adapted to coact with said deflecting plate for directing water in a predetermined path withinthe casingonARLasf onsnivius GOWAN.
